Transcend's SSD upgrade kits for the MacBook Air or Retina MacBook Pro are seeing substantial discounts today on Amazon. The upgrade kits swap out the modular SSD board on older versions of the laptops (alas, they're not compatible with the more recent models) and uses your original SSD as a slim external USB drive. But the deals are only good for today, so if you've been stymied by your limited storage space, you should take a look now.
Here are the discounts that Amazon is offering today and today only:
Apart from the SSD upgrade kits, Amazon is also offering other Transcend storage products at substantial discounts, including a 32GB MicroSD card for $13.99 (63% off), a 64GB MicroSD card for $28.99 (42% off), a pair of ruggedized external USB 3.0 hard drives, and a selection of steeply-reduced USB flash drives (128GB for 74% off ain't half bad).
These prices are good for today and today only, though, so if you're looking to buy, we suggest you do so shortly. We know it's the MacBook SSD kits that really have your attention — who's tempted by a $500 960GB SSD upgrade?

Apple's gotten a lot of attention recently for iOS 7's multipeer networking frameworks. I covered them briefly in my enterprise and education overview back in September 2013 when iOS 7 first launched but they're worth a closer look. Multipeer networking makes use of Bluetooth, Infrastructure Wi-Fi (like a Wi-Fi Hotspot), and Peer-to-Peer Wi-Fi (also called Wi-Fi Direct) to create a peer-to-peer meshed network. Once the network has been established, people on that network can share content including messages (think IM), resources (think documents), or stream content. If you have used AirDrop to share pictures or other content with others, you have already used Multipeer Connectivity without knowing it. This is something risk managers in enterprise are going to love, and here's why!
Multipeer Connectivity allows an app to create a network, and allow others to join it. Once they join the network, they can share content, stream content (like audio or video), and chat.
When iOS7 or later devices are connecting to the peer-to-peer meshed network, they make use of any of the available radios including Bluetooth or Wi-Fi. If there is no available Infrastructure Wi-Fi network (like a Wi-Fi Hotspot), the device will use Peer-to-Peer Wi-Fi (aka Wi-Fi Direct) to join the mesh network.
In fact, when developers create apps to take advantage of the Multipeer Connectivity Framework, they are abstracted from the entire networking processes itself. The framework takes care of automatically selecting the best radio to use (as long as the user has it enabled) and connecting to the network. This means that app developers do not need to be network experts, they just need to build great apps.
iOS7 or later devices can be members of more than one peer-to-peer network session, and iOS7 or later devices can bridge connectivity between members of the same peer-to-peer network session.
If we look at the image below we can see that the iPhone on the bottom right has its Wi-Fi radio enabled, but not its Bluetooth radio. The iPhone on the top has its Bluetooth radio enabled but not its Wi-Fi radio. The iPhone on the bottom left has both its Bluetooth and Wi-Fi radios enabled.
The iPhone on the bottom right can communicate with the iPhone on the bottom left using Wi-Fi. The iPhone on the top can communicate with the iPhone on the bottom left using Bluetooth. However the iPhone on the bottom right can also communicate with the iPhone on the top because the iPhone on the bottom right is acting as a bridge. All of this connectivity is taken care of automatically by the Multipeer Connectivity Framework of iOS7.
Most of us are familiar with a hub-and-spoke network like a Wi-Fi Hotspot or our Wi-Fi network at home. In fact cellular networks are also hub-and-spoke networks. As the name implies, each device on the network connects to all other devices on the network via a central hub as you can see in the diagram below. With a hub-and-spoke network, if the hub does down, no devices can communicate. This is the single point of failure.
On a meshed network, all devices can communicate directly with each other, with no need for a central hub as we can see in the diagram below.
The benefit of a meshed network is that devices on that network do not need a central hub to direct traffic. There is no single point of failure that can stop communications and all devices can communicate with each other freely.
iOS7 Multipeer networks also theoretically have no range limit. Because all devices can communicate with all other devices, and with the added benefit that any device can bridge communications, as long as a device is in-range of at least one other device, communications can remain established.
Risk Managers, amongst other things, spend a lot of time figuring out how to keep a company or government agency working in a disaster. If there is a natural or man-made disaster that knocks out cell towers and Wi-Fi Hotspots, how do companies or government agencies keep communicating with their staff? If cell towers are down, nobody can make calls, but more importantly, nobody can communicate in any way.
With the Multipeer Connectivity Framework of iOS7, apps can be built that take advantage of the meshed network. These apps can provide Instant Messaging (IM), streaming content (probably audio), and updates to documents like evacuation plans, and other important documents.
Imagine employees being able to continue doing their job by remaining in-touch with co-workers and management via IM. Imagine companies or government agencies being able to stream important information via audio to all employees.
iOS7 Multipeer networks can also be encrypted so that information remains private within each network. In addition, authentication can be mandated so that each device must provide login information to become part of the network. These last two features are extremely important to companies and government agencies because while the idea of a meshed network is great, if you cannot secure it, it is useless.
In our hub-and-spoke cellular data and Wi-Fi Hotspot world, we have always been at the mercy of the hub. No hub, no communications. Meshed networks are not new and have been around for decades, however they have not been applied to mobile communications the way they have been in iOS7. Apple has provided a framework that does all of the heavy lifting for developers, allowing them to exploit the power of the meshed network without having to become network experts themselves.
Meshed networks are entirely possible on other platforms including BlackBerry, Android, and Windows Phone/Windows Surface RT, because all of those devices include Bluetooth and Wi-Fi radios, however the operating systems themselves do not have the frameworks in-place to make developing apps that utilize meshed networks easily. For app developers to achieve what can be done on iOS7, they would need to build their own meshed network framework, in addition to the app they wanted to build. This is not an impossible task, however it greatly complicates the process.
To see the possibilities of iOS7’s Multipeer Connectivity Framework, take a look at the FireChat app. It utilizes this technology to offer Instant Messaging even when there is no cellular or Wi-Fi coverage.

Currently in the midst of a very intense season of "The Biggest Loser," Jillian Michaels garnered herself a little added exposure by covering the January 2014 issue of Self magazine.
While showing off her flawless figure for the Chris Craymer photo shoot, the 39-year-old fitness guru revealed some helpful tips about how stay motivated when it comes to losing weight.
Highlights from Miss Michaels are as follows. For more, be sure to pay a visit to Self!
On getting in shape:
"Ask yourself, 'Why do I want to be in shape?' and write all those reasons down. Be specific. I don't know what 'I want to be healthy' means, but I do know what wearing a bikini or fitting into your wedding dress means. Put your list everywhere to constantly remind yourself why you're doing what you're doing and how your life will improve by becoming fitter."
On making goals for yourself:
"Let's say you want to lose 20 pounds in three months. When you reach your weekly goal, get a manicure or pedicure. When you reach your monthly goal, get a massage. When you reach your ultimate goal, give yourself $500 for new clothes. Just make sure the reward is positive and life-affirming and not 'Now I get a night on the town to get s---faced drunk!' No. Never reward yourself with self-destructive things."
On pushing through the pain:
"It's very easy to fall into a victim mentality, where everything that's hard feels like a punishment. But when it comes to your body, it's worth it. I don't love to work out, but I love what it does in my life. I'm not excited about chicken and broccoli again, or the treadmill, but I'm excited about my skinny jeans. Everybody who tries something new starts out crappy, awkward and uncomfortable. Don't look at a struggle as a failure or validation that you're not as good as other people. Every journey begins with a first step."

In November 2014, after traveling 10 years and hundreds of millions of miles, a European spacecraft will touch down on a two-and-a-half-mile-wide ball of ice and dust as it hurtles through space towards the sun. And if all goes according to plan, this unprecedented feat could finally give us what we need to understand the origins of life on Earth. It's just the "according to plan" that's the tricky part.
